Quoting Nick Hilliard <[email protected]>:
from personal experience, I can say that the silence which ensues from a power failure in a data centre is seriously creepy.
Oh yes - I was indirectly the cause of that happening at one hosting location in the Midlands about ten years ago when inserting a Dell blade server into its chassis, somehow the power rails shorted, and dumped about 60A straight through some copper which wasn't man enough for it and which then proceeded to vaporise a chunk of the blade motherboard, and both multi-way connectors (Blade side and chassis side).
One of my guys who was working behind it ended up inhaling a load of incredibly magic smoke, and the DCs VESDA install proved its worth by SCRAMing the entire floor.
Yeah - took a lot of other customers out with it, and we were banned from installing Dell blades at that location ever again.
Not a day long outage - took about an hour to verify that the site was good to restart, and to start feeding power in again, but yeah - the eerie silence after the white noise of several thousand server fans and such t like.....
I bought a hundred and fifty HP DL140G2's straight afterwards and started ripping out the Dell kit.
